PACKING- SPECIFICATION forming part of Letters Patent No. 617,863, datedJanuary 17, 1899.

Application filed February 24, 1898. Serial No. 671,442. fNo model.)

To all 10h/01nz't Vmay cou/cern:

lle it known that I, CHARLES S. RIDER, a citi/en of the United States,residing at Silver Oreck, in the county of Chautauqua and State of NewYork, have invented a. new and useful Improvement inIacking-liiacliines, of which the following is a specification.

This invention relates to that class of packing-machines which are moreespecially designed for filling small packages or sacks with seeds andsimilar materia-l.

'lhe object of my invention is to produce a packing-machine of thischaracter in which the tripping mechanism is simple in construction andreliable in ope .nation and permits of' filling the packagesexpeditiously.

In the accompanying drawings, Figure l is a vertical section of apacking-machine provided with my improved tripping mechanism and showingthe position of the parts at the bcginniugol' the filling operation.Fig. 2 isa fragmentary sectional elevation of the tripping mechanism,showing the position of the parts when the platform is in its lowestposition. Fig, 3 isa fragmentary horizontal section in line l il, Fig.l.. Fig. -l is a fragmentary vertical section, on an enlarged scale, inline -l l, Fig. l.

Like letters` of reference refer to like parts in the several ligurcs.

A represents the main frame of the packing-machine; l, the tablearranged horizontally in the lower portion oi' the frame; C, the supplyhopper or bin mounted. on the upper portion of the frame, and C thevertical lilling-tubc arranged on the outlet at the lower end or thesupply-hopper.

I) represents the vertical feed-shaft arranged in the hopper andiilling-tube and journalcd with its upper portion in a bearing,` (l in across-piece d', while its lower end is provided within the filling-tubewith a pack.- ing screw or auger d?. lhe auger-shaft is driven from ahorizontal driving-shaft F. by a pair of intermcshing` bevel or mitcrgearwheels c, secured,respectively,to these shafts. rl`he driving-shaftis Iiournaled in bearings e on the Cross-piece and is rotatedintermittently by a continuously-rotating drivingpullcy F, mountedlooselyon the driving-shaft` and capable of a reciprocating movement'pose of engaging its friction-face fwith or disengaging the same fromthe friction-face f of a clutch-wheel F', secured to the shaft, therebyoperating or stopping the packingauger. 'lhe longitudinal movement ofthe driving-pulley is effected by an elbow 0r clutch lever G, pivoted toswing in a vertical plane on the cross-piece d and having its upper armg connected with the hub of the driving-pulley, so that the latter iscompelled to move lengthwise of the driving-shaft with the elbow-lever,but is free to turn independently thereof. p i Y Y l' represents thevertically-movable platform, which supports the package to be filled andwhich is arranged on the upper end 0f a vertically-rcciproeating liftingrod or bar 7i The latter slides with its upper portionin a guide-openingh' in the table and with its lower portion in a guit'le-opening h2,arranged in a 'el'ossehar I of the main frame. The platform is elevatedand yieldingly held aga-inst downward movement by a lifting-lever J',which is pivoted by a horizontal pinj to a standard j, arranged. on theeross-harl. The inner arm UP of this lifting-lever is provided with alongitudinal slot ji, which receives a pin or projection on theplatform-rod l1, andy the outer arm of the lever provided with a\\'eightj, w lich is capable of lengthwise adjustment on the respectivearm.

l( represents a shitting-lever whereby the driving mechanism is coupledwith and uncoupled from the feed mechanism and which is arranged lengthwise above the lifting-lever. This level' is pivoted by a horizontal pinto a hanger le on the under side of the table, and its inner arm ;e isarranged over a shoulder or pin /f on the platform-rod, while its outerarm le" is connected by an upright rod 7.3 with the lower arm g' of theclutch-lover G.

I. represents a vertical catch-har whereby the cluieh may he held in itscoupled position duringr the packing operation and the piatforin maybeheld in its depressed position while replacing the filled package by anempty package. The watch-bar is pivoted at its upper end to the underside of the table, so as to swing i ransversely to the shifting andlifting levers, and provided with an overlengthwise of the driving-shaftfor the pur- IOO hanging weight whereby it is yieldingly pressed againstthe rear sides of these levers. 'lhe eatclrbar is provided near itsuppercnd with an upwardly-faeing shoulder nl, and with an incline or eamface nl', arranged below the shoulder and leading to the outer orfrontend thereof. l'pon raising the inner arm ofthe shiftingllever forcoupling the driving-pulley with the feed mechanism the lever engageswith the incline ni' of the catch-bar and dellects the latter rearwardlyand then passes above said shoulder m, which permits the catclrbar toswing forwardly by gravity, so that its shoulder m stands under theshifting-lever and prevents the latter from descending, thereby holdingthe driving and clutch pulley in a coupled position for operating thepacking-auger. Upon moving the 'catclrbar rearwardly its shoulderf//L isdisengaged from the shifting-lever, the inner arm of this lever drops,owing to its prepondcrating weight,and its outer arm discngages thedri ving-pulley from the clutch-pulley through the medium of theconneetingrod /F and clutchlever (l, thereby stopping the operation ofthe auger.

N represents a catch block or plate arranged on the front side ofthecatch-bar and provided with a down ward ly-facing shoulder n and with anincline or cam face nl, arranged above the shoulder and leading to theouter or front end thereof. 'lhe catch-block is capable of verticaladjustment on the catch-bar and is connected with the latter by a clamping-screw n2, engaging with the block and passing through a verticalslot n in the catch-bar. During the downward movement of the inner armof the lifting-lever with the platform-rod this arm engages with theincline of the catchblock and deflccts the same backwardly, togetherwith the catch-bar, thereby dlsengaging the upper shoulder m from theshiftinglever. Upon depressing the inner arm of the lifting-lever intoits lowestposition the same is carried below the shoulder n of thecatchblock and thelattcr, together with the catchbar, swings forward bygravity, so that its shoulder stands above the inner arm of thelifting-lever and prevents the same from rising, thereby holding theplatform and con meeting parts in a depressed position.

t) represents a vertically-movable rolcas ing-rod whereby the catch-barmaybe shifted for disengaging its shoulders from thc shifting andlifting levers and which is guided with its upper portioir in aguide-opening o in thc table and with its lower portion in a guide il onthe cross-bar I of the frame. This releasing-bar is depressed by meansof a handle og, secured to its upper end, and it is yieldingly held inan elevated position by a spring o, hearing with its lower end againsthanger oi on the table and with its upper end against a shoulder or pino" on the rclcasing-rod.

1 represents a collar secured to the lower portion of the releasing-harby a. set-screw p and provided with a rearward]y-projccting lug ortappet p. The latter is provided with an inclined rear end which isadapted to cngage with a forwardly-projeeting toe or lng 1F on the lowerend of the catch-bar and move the latter rearwardly.

j represents an upright guide-bar, which engages with the front sides ofthe shifting and lifting levers and holds the rear sides thereof againstthc platform-rod and which is secured with its ends to the table andcrossbar I.

In the operation of my machine the platform is elevated by thelifting-lever so as to support the package, which has been slipped overthe filling-tube, and the inner arm of the shiftinglever is engaged withthe upper shoulder of the catch-bar, (as represented in Fig. 1,) inwhich position of the parts the package is being filled. As the lillingof the package proceeds the platform is gradually depressed, togetherwith the inner arm of the lifting-lever, by the action of thepackingauger, but the inner arm of the shiftinglever is held in anelevated position by the upper shoulder of the catch-bar. When thedesired quantity has been fed into the package, the inner arm of thelifting-lever in its descent with the platform engages with the lowerincline a of the catch-bar and dcllccts the same rearwardlysufficientlyto disengagc its upper shoulder m from the inner arm of thesliifting-lever, thereby permitting' the latter to drop and disconnectthe driving mechanism from the packing mechanism for stopping thefilling of the package. '.lhe operator now deprcsses thc platform nntilthe iniier'arm of the lifting-lever is engaged with the lower shoulder nofthe catch-bar, whereby the platform is held in a depressed position,as represented in Fig. 2. The operator now replaces the filled packageby an empty package and then dcpresses the rcleasing-bar, whereby thelower shoulder of the catch-bar is disengaged from the inner arm of thclifting-lever and the latter is raised by the weight ji, together withtho platform and its rod. During the latter portion of the upwardmovement of the platform-rod the pin or shoulder 7.5 engages with thcinner arm of the shifting-lever and lifts the same above the uppershoulder m on the catch-bar, thereby coupling the d riving.,r mechanismwith the feeding mechanism and starting filling of thc package.

I claim as my inventionl. 'lhe combination with the verticallymovableplatform and the rod extending vdownwardly therefrom, the feedmechanism,

the driving mechanism, and the clutch connecting the driving mechanismwith the feed mechanism, of a shifting-lever connected with the clutchand adapted to be lifted bya projection on the platform-rod to throw theclutch into gear, a movable catch-bar provided with a shoulder which.`engages under thc shift ing-lever after the same has been lifted and IOCIIO

holds the same in its elevated position, and a weighted lifting-leverconnected with the platform-rod to move up and down therewith, saidlifting-lever engaging with an incline on said catch-bar at the end ofthe downward stroke of the platform and releasing the catchbar from theshifting-lever, thereby allowing the same to drop and uncouple theclutch, and said lifting-lever also operating to lift the platform whenthe same is released, substantially as set forth.

2. The combination with the verticallymovable platform and the rodextending downwardly therefrom, the feed mechanism, the drivingmechanism, and the clutch connecting the driving mechanism with the feedmechanism, of a shifting-lever connected with the clutch and adapted tobe lifted by a projection on the platform-rod to th "ow the clutch intogear, a lifting-lever connected with the platform-rod to move up anddown therewith, a movable catch-bar provided with a shoulder whichengages under the shifting-lever after the me has been lifted and holdsthe same in it?1 elevated position, and a releasing and lock ng blockarranged on said catch-bar and provided with an incline against whichthe lifting-lever engages, to release the shoulder of the catch-bar fromthe shifting-lever at the end of the downward stroke of the platform,and below said inclino with' a shoulder which engages over thelifting-lever after the shifting-lever has been released and whereby thelifting-lever and the platform are locked in their depressed position,substantially as Set forth.

" The combination with the verticallymovable platform having alifting-rod, the feed mechanism, the driving mechanism and the clutchadapted to couple and uncouplo the driving mechanism and the feedmechanism, of a lifting-lever connected with vsaid lifting-rod, ashifting-lever connected with said clutch and adapted to be engaged by ashoulder on said lifting-rod, a movable catchbar provided with shouldersadapted to engage with the lifting and shifting levers, and avertically-movable releasing-rod provided with a tappet adapted to shiftsaid catch-bar, substantially as set forth.

4. The combination with the verticallymovable platform having alifting-rod, the feed mechanism, the driving mechanism and the clutchadapted to couple and nncouple the driving mechanism and the feedmechanism, of a lifting-lever connected with said lifting-rod, ashifting-lever connected with said clutch and adapted to be engaged bya' shoulder on said lifting-rod, a pivoted catchbar provided withshoulders adapted to cn` gage with the lifting and shifting levers, averticallymovable releasing-rod provided with an inclined tappet adaptedto engage with a projection on the catch-bar, and a spring whereby thereleasing-bar is yieldinglyheld in an elevated position, substantiallyas set forth.
